Precision Voltage Reference in a Tiny 2mm × 2mm DFN Package

Jan 25 2006 -MILPITAS, CA
  • Linear Technology Corporation announces the LT6660, the industry's first precision series voltage reference to use the tiny 3-lead 2mm × 2mm DFN package. These compact devices combine 0.2% initial accuracy and 20ppm drift with micro-power operation and require less than half the space of the SOT-23 package. Furthermore, the LT6660 does not require an output compensation capacitor - a key advantage where PC board space is at a premium or fast settling is required.

    The LT6660 accepts input voltages up to 30V and can withstand reverse-battery conditions. The output voltages include 2.5V, 3V, 3.3V, 5V and 10V. With a dropout of only 900mV, this tiny device is also ideal for precision regulator applications since it can supply up to 20mA of current. Since it needs no output compensation capacitor, the LT6660 is also suited to applications with intrinsic safety requirements.

    The LT6660 offers a way to significantly reduce the size of new designs without compromising performance. "The LT6660 combines an excellent set of features and precision specifications in only 4mm2," says Brendan Whelan, design section lead for Linear Technology.

    The LT6660 is in full production, with prices starting at $0.88 each in 1,000-piece quantities.
